Description

The tap water cut-off automatic safety device

The utility model relates to a kind of valving, particularly a kind of tap water cut-off Protective valve device.

The water supply pipe of dwelling house, public place is directly mounted thereto valve at present.Because valve generally is manually operated, under the situation that valve is forgotten to close, the accident that dwelling house floods often takes place when supplying water once more at tap water cut-off, this will waste many water resourcess, and also the life to people brings a lot of inconvenience.

It is a kind of when forgetting throttle down that the purpose of this utility model is to provide, with the automatic-closing valve automatic safety device that prevents that tap water from supplying water again.

The purpose of this utility model is achieved in that the utility model mainly is made up of casing, baffle plate, ball float, first connecting rod, second connecting rod, third connecting rod, the 4th connecting rod, hook, rubber pad, valve, intake pipe, outlet pipe.Casing is divided into water-inlet cavity and water chamber by the baffle plate that downside is provided with water-guiding hole, and a side of water-inlet cavity is fixed with intake pipe, and the part of outlet pipe is in water chamber, and another part is drawn by the water chamber bottom.Be provided with ball float in the water-inlet cavity, one end and the floating ball body of first connecting rod fix, the rotating shaft in the other end and the casing outside fixes, the two ends of rotating shaft respectively with casing on supporting frame be hinged, one end of second connecting rod and the top of ball float fix, the other end strides across baffle plate and third connecting rod is hinged, one end of third connecting rod and an end of hook are hinged, the other end of third connecting rod is hinged by a pitman shaft and an end that is fixed with the 4th connecting rod of rubber pad, the other end of the 4th connecting rod forms the skewed slot shape, with the corresponding configuration of hook, the 4th connecting rod is connected by hinge with a side of outlet pipe simultaneously.Rubber pad is provided with valve corresponding to the water outlet of outlet pipe upper end in the inside of outlet pipe, and constitutes one with driving lever, and driving lever is corresponding to hook.

Under the situation of normal water supply, water is arranged in the casing, ball float drives second connecting rod, third connecting rod and hook come-up, third connecting rod is upwards carried an end of the 4th connecting rod by pitman shaft, this moment the rubber pad breakdown, water can flow out from water outlet.

Under the situation that valve is forgotten to close cutting off the water, the water of water-inlet cavity flows out from the water-guiding hole that is located at the baffle plate downside, ball float loss of buoyance and drive second connecting rod, third connecting rod and hook falls, the gravity of ball float and second connecting rod, third connecting rod and hook reaches on the rubber pad, make rubber pad cover water outlet, hook is taken advantage of a situation and is hung up the counterpart of the 4th connecting rod.When supplying water once more, the ball float desire is floating, and hook is because of breaking off relations, and buoyancy transfers the pressure to rubber pad to, makes it firmly cover water outlet, at this moment, as wants the breakdown water outlet, only valve handle can need be driven driving lever and pushes hook aside once stubborn.

The utility model is simple in structure, easy to operate, safe and reliable, can be made into large, medium and small type all size, is suitable for also can being directly installed on the pipeline tip on the water supply pipes such as dwelling house, public place.

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is a front schematic view of the present utility model.

Fig. 2 is that schematic representation is looked on the right side of the present utility model.

Fig. 3 is a schematic top plan view of the present utility model.

Among Fig. 1 and Fig. 21, casing 2, baffle plate, 3, water-inlet cavity 4, water chamber 5, ball float 6, rotating shaft 7, first connecting rod 8, second connecting rod 9, third connecting rod 10, hook the 11, the 4th connecting rod 12, pitman shaft 13, rubber pad 14, water outlet 15, valve 16, driving lever 17, water-guiding hole 18, intake pipe 19, outlet pipe

Casing 1 is divided into water-inlet cavity 3 and water chamber 4 by baffle plate 2, and baffle plate 2 lower ends have water-guiding hole 17, and intake pipe 18 is fixed on a side of water-inlet cavity 3, and the part of outlet pipe 19 is located in the water chamber 4, and another part is drawn by water chamber 4 bottoms.Be provided with ball float 5 in the water-inlet cavity 3, one end and the ball float 5 of connecting rod 7 fix, the rotating shaft 6 in the other end and casing 1 outside fixes, the two ends of rotating shaft 6 respectively with casing 1 on supporting frame be hinged, the top of ball float 5 is fixed with second connecting rod 8, second connecting rod 8 strides across baffle plate 2 upper ends, hinged with third connecting rod 9 one ends that are located in the water chamber 4, the same end of third connecting rod 9 is hinged with hook 10, the other end of third connecting rod 9 is hinged by a pitman shaft 12 and an end that is fixed with the 4th connecting rod 11 of rubber pad 13, the 4th connecting rod 11 is hinged on outlet pipe 19 tube walls simultaneously, and rubber pad 13 just in time forms the skewed slot shape corresponding to the other end of water outlet 14, the four connecting rods 11 of outlet pipe 19 upper ends, with hook 10 corresponding configurations, in outlet pipe 19 inside valve 15 is installed, valve 15 constitutes one with driving lever 16, and driving lever 16 is corresponding to hook 10.

The utility model is an enclosed construction, and wherein valve 15 is a ball valve.The effect of baffle plate 2 is that anti-sealing directly flows out from water outlet 14 under the very thin situation of current, cause ball float 5 to float, the height of baffle plate 2 can not influence moving up and down of second connecting rod 8, water-guiding hole 17 and water outlet 14 lean against casing 1 bottom as far as possible, make the not water of trying one's best in the casing 1 when valve 15 is forgotten to close when cutting off the water.
